http://earthsky.org/space/first-notable-solar-flare-of-2015

First notable solar flare of 2015

Topics that may form the basis of PhD projects in Solar plasma physics group are broadly related to: (i) The magnetic energy release in solar atmosphere (The Solar coronal heating problem) and (ii) Particle acceleration (e.g. in Solar flares, Earth magnetosphere Auroral zone, Tokamaks and Particle Accelerators as SLAC). The research work mainly involves large-scale numerical simulations (Particle-in-Cell, Vlasov and Magnetohydrodynamic (MHD)). Research areas available for PhD study include:
(1) Novel particle accelerator concepts, plasma wake field acceleration;
(2) Enhanced Dissipation of MHD waves in inhomogeneous plasmas;
(3) Collisionless magnetic reconnection;
(4) Particle acceleration by dispersive Alfven waves;
(5) Electron acceleration by Langmuir waves;
(6) Radio emission mechanisms from accelerated electrons;
(7) Radio data analysis of Type III solar radio bursts from the Chilbolton LOFAR Station;

Recent and Current PhD projects include "Numerical and theoretical modelling of radio emission from solar flare electrons (Roman Pechhacker, started in 2010, graduated with PhD in December 2013)" and "Collisionless magnetic reconnection in X-point collapse (Jan Graf von der Pahlen, started in 2012)"
